WALL-COVERINGIN IMI'I'ATION OF REAL TAPESTRY.

Specification of Letters Patent. Patented Feb. 18 1913 Application filed June 10, 1909. Serial No."501,402.

a land, have invented certain new and useful Improvements in Wall-Coverings in Imitation of Real Tapestry, of which the following. is a specification.

The object of this invention is to produce a material the surface of which has the appearance of tapestry, under which term I include not only true tapestry but also artificial or imitationtapestry with or without a decorative design or pattern. For this purpose I take a suitable foundation such as plain undyed hessian, wool, cotton, ramie,

jute or other" suitable fabric and either stencil upon it the design or designs before treating it as hereinafter described to produce the tapestry texture effect, or I may first treat it to produce the tapestry texture effect and afterward stencil the design or designs upon it if such'designs are desired. To produce the said effect, I project onto the surface of the plain or previously stenciled canvas numerous specks of color more or less closely placed,using for this purpose a comparatively thick or strong solution of dye of the desired color which is thrown on by means of an air pressure sprayer or air brush, the air pressure of which is regulated so as to throw .the color in the form of smalh globules or drops. In the same way I' may project another color or colors if more than one color is desired. By suitable manipulation of the sprayer the surface is covered in this manner with specks of color or colors uniformly distributed thereover more or less closely according to the effect'and tint desired and in which, if more than one color is used, any of the colors may predominate if desired; Having distributed comparatively dense specks of color or colors in this manner, the surface is 45 damped and rubbed over to blend the color J or colors with the background in such a manner as not to obliterate the speckled effect but rather to soften the outlines of the specks and blend them with the background. By this method the surfaceassumes the appearimce of a woolen texture. If a pattern or design is to be' stenoiled over the surface thus treated, comparatively thin solutions of dye are used for this pattern or design in order that the speckled effect may not be the pattern 'but may show through the same.

In carrying out my invention, I take a quality or texture of plain undyed hessian, wool, cotton, ramie, jute or other.suitable fabric, and distribute over the surface by means of a low air pressure spray, preferably at 9 to 12 lbs. pressure per square inch any desired color in small specks of strong dye solution, according to the strength of color required, following this operation by a distribution of water by the same process, thewater being at a temperature of 50 degrees centigrade and a mordant' such as alumina. or other suitable fixing-agent being added to the water to permanently fix the colors in the fabrics. The plain dyed tapestry eflects of the foregoing process are completed by lightly rubbing the entire surface of the fabric with a moist chamois leather or other siinilar absorbent and the materials hung up to dry. For the decorated tapestry Wholly concealed by the color or colors of l designs 1n various colorings, the groundwork is produced by the application of the foregoing process, using a weak solution of dye only, at an air pressure of .15 lbs. to the square inch to produce the desired shade, after which the designs are printed in their various colorings by a series of multiplex stencilings in one continuous operation, that is to say, the fabric is placed upon'a suitable fiat surface and treated by a number of operatives using stencil plates in such a manner that one color is applied after the other continuously. I

The stenciling is efiectedby having a sepa-' rate plate for each color required in the de sign, the work being done on a large table Very quickly, by two or more operations following each other consecutively as may be necessary, the material being hung up to .dry' as completed. The colors are worked into the fabrics while slightly damp with large round brushes from 2 to 6 inches in diameter. The whole surface is then finally toned by a distribution of small specks of color, of various tones to produce the stitch and-woven efiects, these specks being dis tributed by spraying at a pressure of 15 lbs. to the square inch,-the surface being finally blended by passing a soft stip ler, Turkey sponge, or other suitable blen er over the whole.

I am aware that it has been previously proposed to produce a speckled or granulated appearance on fabrics by means of a spray or blast of coloring matter, and also that it is not broadly novel to apply patterns to fabrics by meansof stencils and no claim er se is made to either of these operations, ut

What "I claim as my invention and desire to secure by Letters Patent of the United States is 1. The method of producing imitation tapestry which consists in spraying under pressure globules or specks of color with suitable dispersion directly over the entire surface of an uncolored foundation of textile material, spraying water under pressure and with suitable dispersion over the Whole surface of the textile foundation to substantially flood the same and lightly rubbing the entire surface so treated to soften the color- 7 efiect of the globules or specks.
